' NEW YORK, N. Y.

PAER BAG.

Application filed .Tune 9, 1922. Serial No. 567,002.

To all whom it may concern:

`Be it known that I, ZENO LrrTMAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful linprovements in Paper Bags, ofwhich the following is a specification.

rlhis invention relates generally to containers or envelopes of the typein which flap closure members are employed and particularly relates tothe construction of i1n proved closure means.

The general objects of the invention are to provide envelopes orcontainers of the type referred to in which the security of the closingor sealing means is greatly increased over the security afforded bysealing -devices heretofore employed, and in which the closure means canbe opened with the greatest ease to provide access to the contents ofthe container.

In the particular disclosure of the invention made herein I show anddescribe an envelope of the general type used in mailing photographs,pamphlets and the like, the envelope being provided with a double liapclosure construction so arranged that one flap forms an extension of oneof the walls of the envelope while the other flap is attached to theinner surface of the other wall along a line spaced from the adjacentend of the wall. This arrangement provides for the folding of the secondflap over the contents of the container and also the folding of theiirst flap over the second flap and into the pocket formed between thesecond flap and the wall to which it is attached. It will be seen thatthis structural arrangement provides a double closure which effectuallyprevents the accidental removal of the contents of the envelope.

I provide also for facilitating the withdrawal of the iaps from closedto open position by the provision of suitable tabs which can be readilyseized between the lingers to pull out the tabs from their closedposition.

In the drawings,

Figure 1 is a view in front elevation of an envelope embodying theinvention.

Figure 2 is a sectional view on an enlarged scale of the upper end ofthe envelope shown in Figure 1 with two closure flaps shown in openposition.

Figure 3 is a view similar to Figure 2 showing one of the flap membersfolded into closed position.

Figure t is a view similar to Figure 3 showing both flap members` infolded position.

Figures 5, G and 7 are 'views corresponding to Figures 2, 3 and 4f,respectively and showing the provision of linger tabs for use inwithdrawing the flap members from closed position.

Referring to the drawings in Figure 1 there is shown an envelope 5 of asuitable type in which to mail photographs, pamphlets and other articleswhich it, is not desired to seal against inspection at the cost offirst-class postage. In order to provide a closure which will satisfythe postal regu lations relating to ready inspection and at the sametime provide a secure closure which will prevent the accidental removalof the contents of the envelope in transit through the mails, I make useof two closure flaps 6 and 7 which can be utilized to provide a doubleclosure for the open end ot' the envelope.

The closure flap 6 forms a simple extension of the rear wall 8 of theenvelope 5 while the other flap 7 may be formed integrally with orattached to the forward wall 9 of the envelope in such manner as to forma pocket 10 between the wall and the outer face of the flap. Preferablythe depth of the pocket 10 is substantially the same as the extension ofthe rear closure flap 6 from the end of the wall 8. The closure iap 7may be attached to the end of the envelope wall 9 at 11 and pasted tothe wall as a reinforcement thereof as indicated in Figure 2 of thedrawing, or attached to the wall at the point 12 to forni the closed endofthe pocket 10. It will be clear that if the liap 7 is integral withthe wall 9 it will be folded back on the wall at the point 1l.

lVith the structural arrangement disclosed, and referring to Figure 3,the for ward closure flap 7 in closing the envelope is first folded overthe envelope contents 13 as indicated. This is followed by the foldingof the rear flap 6 over flap 7 and into the pocket 10 as indicated inFigure et. This completes the closing operation and the contents 13 ofthe envelope are held in place b v a double set of closure Flaps as willbe apparent.

ill)

lll() Referring to Figures 5, 6 and 7 of the drawings, finger tabs 14and 15 are attached to the closure flaps rand 7 or are formed integrallytherewith. The tabs 14 and 15 'form convenient members for facilitatingthe withdrawal of tabla and flap 7 to open position when the contentsfofthe envelope can be readily inspected or removed.

l/Vhat claim is: f

1. In an envelope, a closure flap forming an extension of one wall ofthe envelope, and a second closure flap member attached to the innersurface of the other wall at the end thereof and folded back along saidwall for a distance substantially equalling the 'extension of the otherflap beyond the end of the wall, said second closure member being folcedback on itself at and extending` inwardly from the open end of theenvelope to a distance substantially equal to theprojection of theotheriap member.

2. In an envelope, a closure fiap forming an extension of one wall ofthe envelope, a closure flap attached to the inner surface of the otherwall at a point spaced from the adjacent end of the wall, andlextendingsub,- stantially to the free end of the first-named flap, and a lingertab carried by one of said closure flaps in position to be grasped whenthe closure flap is in closed position.

l 3. In an envelope, a closure ilap forming an extension of one wall ofthe envelope, a closure flap attache-d to the inner surface of the otherwall in such manner as to forma pecliet in which to receive vthefirst-named eiosnre flap, said closure flap extending substantially tothe free end of the first-'named flap, and a linger tab member carriedby each of said closure flaps in position to be grasped when the closureflaps are in closed position.

l. In an envelope, a closure flap forming an extension of one wall ofthe envelope, a closure fiapattached to the inner surface of the otherwall in such manner as to reinforce the wall and form a pocket in whichto receive the first-named closure flap, said closure flap extendingsubstantially to the Vfree end of the first-named flap, and a finger tab:'t'tached to the rear surface of each of the flaps in such manner thatthe one endl of each tab is accessible when the corresponding flap is infolded condition.

in testimony whereof I' aflix my signature;
